Remaining CO2 budget for 2°C global warming used up on:
Remaining time:
18 years9 months17 days23 hrs.52 min. 4 sec.
Remaining amount of CO2 emissions to limit temperature rise to 2°C:
718.693.822.968.272 kg
Remaining CO2 budget following the IPCC Special Report SR 1.5 (IPCC 2018)
1.5° C = 350,000,000,000,000 kg (350 gigatons = 350 trillion kg)
2.0° C = 975,000,000,000,000 kg (975 gigatons = 975 trillion kg)
Please note: IPCC SR 1.5 increased the still available CO2 budget compared to earlier estimates. The budget available in 2015 (the year of the Paris Conference) is now 1084 gigatons instead of 750 gigatons. Thus the date when this budget expires jumped from 2034 (in an earlier version of this climate doomsday clock) to 2045.

*Note: Not included is the distortion caused by the export and import of goods and services, the so-called "grey energy". If this is included in the calculation, the per capita emission of CO2e increases from 9.15 tons to 11.6 tons per German citizen (source: UBA).

Mankind had had 75 years to emit carbon dioxide at the then emission rate in the year of the Rio de Janeiro UN Climate Conference in 1992. Now, in 2024, there are only about 19 years left at the present emission rate to keep global warming under 2 degrees. The available time runs out - action is urgently needed - TIME 2 ACT!
Global climate doomsday clock - it is still time to achieve the 2°C limit.
Our contribution for more protection of the global climate.
